    • Ctrl-C will not do what you expect, use Ctrl-Shift-C, or click mouse wheel
    • There are many better terminal emulators that XTerm
    • If you accidentally press Ctrl-Alt-F1, you can press Alt-F7 to switch back to the graphical desktop
    • There are in fact many ways to exit vi, no need to reboot your PC
    • There’s no need to suffer through The True Commandline Experience For Real Fedora-Wearing Sysadmins⁽¹⁾, just install mc and get all the benefits without typing cd and ls every time you want to find a specific file

    ⁽¹⁾ Real Fedora-Wearing Sysadmins don’t use vi to edit files, they either write a sed script or use cat to copy the file to the terminal, then use cat again to copy the contents of the terminal back into the file by clicking the mouse wheel while typing manually the lines they need to change.



  • Capsules are considered more advanced drug packaging because none of the drug dissolves in your mouth when you swallow capsules. Unlike pills, 100% of the drug goes straight to your stomach, so there’s no variation in the drug dosage, and the patient won’t complain if the drug is bitter.

    Also because you can open the capsule and pour it into the glass of water, if you have trouble swallowing pills. Which defeats the first advantage, and you can simply order powdered drug instead of pills, but it won’t come pre-packaged as pills so it will be more expensive.

    None of that matters for vitamins, you generally need more than 1000% of the daily dose for it to become harmful, so each pill contains more than your body really needs, because there are no side effects, so you can buy a pill and lick it, chew it, crush it, and add it to your coffee, and it will still work just fine.


  • You can listen to FM radio with gqrx relatively easily, if you can navigate through hundreds of input boxes.

    sudo apt-get install gqrx
    

    Anything more complicated will require some coding knowledge, unless someone already created a library for that specific thing.

    There is also a ready-made package to listen to GPS signal, unfortunately it needs an external amplifier and a proper antenna, because RTL-SDR is not sensitive enough for GPS.

    I first used Matplotlib 10 years ago. It was unintuitive and very slowly redrawing the whole plot each time you tried to zoom.

    I’m using it right now, and I’m happy to report that it kept to it’s time-honored tradition - zoom is still piss-slow even on my fancy new PC with 12 cores.

    Maybe in the next 20 years, matplotlib devs will discover wonders of tile cache.










  • Nobody here cares what os they use in their office pc.

    Yup, that’s how it’s supposed to be. You turn on your PC to get your office work done, not to reinstall display drivers each day.

    Gone are the days when you needed to compile your own modem drivers to access Internet from your Linux PC.

    The Linux experts here are using their technical knowledge to perform advanced tasks like setting up server clusters for AI-generated furry porn, they are definitely not the ‘average’ Linux user.
